Use the "Restrict by date" option to limit the your search
to documents that were published during a specific time period or single
date.

The default restriction is for the "Previous 2 years," which
means the system will only return those items satisfying your search criteria
that have been published or made available to the general public in the
two years up to today's date.

To change the date restriction for your search, select an option from
the "Restrict by date" drop-down list. Depending
on your selection, the system will display one or more customizable fields
for configuring your restriction.
